The spindle is provided below the upper shoulder a with a second shoulder, a', between which and the collar of the upper bearing` B a small annular oil chamber or reservoir is formed ,'which surrounds the shoulder a.

The lower bearing,` C extends into a cupsliaped support, D, that takes up any surplus oil running down along the spindle, so as to prevent anyloss of oil.

The upper bearing` B is provided ,with two or more annular recesses, d, and communicating holes, that open into the cup-shaped top part of the bearing part to conduct the oil down along' the spindle into the chamber or reservoir around the shoulder a, and supply A spindle having a collar or shoulder rest-l ing` on the lower bearing of thesurrounding box, and acting` as a valve or stop to prevent the oil from lowing down along the spindle, substantially as set forth.
